【摘要】：水电能源是绿色、清洁、可持续发展能源。截至2015年年底,我国水电装机容量3.19亿千瓦(占全球水电装机容量的27%),发电量11143亿千瓦?时,较2010年我国水电发电量的7210.20亿千瓦?时增长了3932.8亿千瓦?时,这得益于“十二五”期间一批大型、特大型水电工程项目的竣工、投产。“十二五”期间,借助于“溪洛渡、向家坝”等一批特大型水电站的竣工、投产,我国水电发电量迅速增长,我国水力发电装备制造技术也有了很大进步。但与国外先进水平相比,我国在水轮发电机组先进控制技术、智能化水电站建设、水电大数据分析和数据挖掘技术等方面,还有一定差距,还需要今后努力追赶。论文主要介绍了水轮发电机调节系统数学模型,论述了智能控制策略在水轮发电机控制中的应用,针对黄河大峡水电站1号水轮发电机现有功率调节过程的不足,提出了一种基于模糊自适应PID的水轮发电机功率调节算法,并利用Matlab/Simulink对算法进行了“阶跃响应、空载试验、甩负荷试验”等三个水轮发电机典型实验的计算机模拟仿真,仿真结果表明算法鲁棒性良好、PID参数可以自适应。论文研究成果对于优化黄河大峡水电站1号水轮发电机组控制系统性能,提高控制系统效率,具有重要的指导意义和现实意义,是未来智能化水电站的研究方向。
[Abstract]:Hydropower energy is green, clean and sustainable energy. By the end of 2015, China's hydropower installed capacity was 319 million kilowatts (accounting for 27 per cent of the global hydropower installed capacity) and generated 1.1143 trillion kilowatts of electricity. Compared with 721.02 billion kilowatts of hydropower generation in China in 2010? Time increased by 393.28 billion kilowatts? This benefited from the completion and commissioning of a number of large-scale and super-large hydropower projects during the 12th five-year Plan period. During the 12th five-year Plan period, with the help of the completion of a number of super-large hydropower stations, such as Xiluodu and Xiangjiaba, the hydropower power generation in China has increased rapidly, and the manufacturing technology of hydropower equipment in China has also made great progress. However, compared with the advanced level of foreign countries, there are still some gaps in the advanced control technology of hydro-generator set, intelligent hydropower station construction, hydropower big data analysis and data mining technology, which still need to be caught up in the future. This paper mainly introduces the mathematical model of hydrogenerator regulation system, discusses the application of intelligent control strategy in hydrogenerator control, and in view of the shortcomings of the existing power regulation process of No. 1 hydrogenerator in Daxia Hydropower Station of the Yellow River, puts forward a power regulation algorithm of hydrogenerator based on fuzzy adaptive PID, and carries on the step response and no-load test of the algorithm by using Matlab/Simulink. The typical experiments of three hydrogenerators, such as load rejection test, are simulated by computer. The simulation results show that the algorithm is robust and the PID parameters can be adaptive. The research results of this paper are of great guiding and practical significance for optimizing the control system performance of No. 1 hydro-generator set of Daxia Hydropower Station on the Yellow River and improving the efficiency of the control system. it is the research direction of intelligent hydropower station in the future.
